,This invention relates to improvements in been oun dnecessary to also include the ordinary hand'starting system-which may: be i used inthe event that the self starter fails to perform its function. As the. crank shaft, to which the hand crank is connected, usually projects-outwardlyfrom the front portion of the machine and presents an unsightly appearance and becomes covered with dust and dirt within a short time, caps have been provided for covering'the outer ends of the crank shafts but it has heretofore been found diflicult to prevent the removable ortions ofthe caps from disengaging the ed portions. and becoming acci- It is one of the objects of the present .invention to overcome the before mentioned objectionable features and provide a crank shaft cap which may be easily fastened to the machine and in which the removable end cover portion is securely locked closed position against accidental disengagement.

A furtherobject of the invention is to provide a crank shaft cap which is of simple construction is strong and durable and is' well adapted .40

for thepurpose desired. With the above and other objects in view the invention consists of the improved crank shaft cap and its arts'andcombmatlons as qsetforth in the-caims, andallequivalents'; i
